[tex] \frac{5}{8} \times \frac{56}{45} simplificam \: cu \: 8 \: si \: 5 = \frac{1}{1} \times \frac{7}{9} = \frac{7}{9} [/tex]
[tex] \frac{16}{49} \times \frac{7}{8} simplificam \: cu \: 7 \: si \: 8 = \frac{2}{7} \times \frac{1}{1} = \frac{2}{7} [/tex]
[tex] \frac{4}{3} \times 2 \frac{1}{6} = \frac{4}{3} \times \frac{13}{6} = \frac{52}{18} = 2 \frac{16}{18} [/tex]
Dacă te-ai referit la 4/3 din 21/6 = 4/3×21/6=84/16 simplificam cu 4 = 21/4
